I would suspect that the two contacts you have are not exactly alike. Maybe the doping distribution or size is slightly different for the contacts?

Shigeo Kubota

Jeong, What kind of input power are you talking about? Is it high enough to ignore dark current? Shigeo

Ravi Singh

I too have got the same non-origin I-V for dark current. Could anyone throw some light on it.
